Abstract

An apparatus and method for generating a multiplex of media streams, the method includes the steps of: (i) receiving a set of media streams that comprises first type media stream components and second type media stream components; (ii) applying a modification process that is not adapted to modify second type media stream components, such as to provide at least one modified first type media stream component; and (iii) multiplexing at least the second type media stream components and the modified first type media stream components.

Claims (19)

1. In combination with other steps prior art fails to teach alone or in combination the limitations of applying a modification process that is not adapted to modify second type media stream components thereby providing at least one modified first type media stream component, wherein the modification process includes modifying a size of at least one media stream component of the group, evaluating the size of the at least one modified non-encrypted media stream component, and determining whether additional modification is required.

2. The method of claim 1 wherein the second type media stream packets are encrypted such as not to facilitate their modification.

3. The method of claim 1 wherein the modification process involves lossy compression.

4. The method of claim 1 wherein the modification process' involves lossless compression.

5. The method of claim 1 wherein the modification process involves altering a size of at least one media stream component.

6. The method of claim 1 wherein the modification process involves altering a timing of transmission of at least one media stream component.

7. The method of claim 1 wherein the step of multiplexing further comprises multiplexing non-modified first type media stream components.

8. The method of claim 1 wherein the step of modifying comprises executing modification sessions in a periodical manner.

9. The method of claim 8 wherein each modification session is associated with a group of media stream components that are received during a certain time period.

10. The method of claim 8 wherein each modification session is associated with media stream components of a certain aggregate size.

11. The method of claim 8 wherein each modification session is associated with a group of media stream components to be transmitted during a certain time period.

12. The method of claim 8 wherein each modifications session is associated with media streams components of the set of media streams that were not transmitted.

13. The method of claim 8 wherein at least one modification session includes modifying a timing of at least one media stream component of the group, evaluating the timing of the at least one modified non-encrypted media stream component, and determining whether additional modification is required.

14. The method of claim 12 wherein the additional modification comprises modifying a non-modified non-encrypted media stream component of the group or re-modifying a modified media stream component of the group.

15. The method of claim 1 wherein at least one media stream of the set is partially encrypted.

16. The method of claim 1 further comprising determining at least one control parameter.

17. The method of claim 16 wherein the determination is followed by selecting an encrypted version of a media stream out of multiple distinct encrypted versions.

18. The method of claim 17 wherein the distinct encrypted versions differ from each other by a parameter that is video quality, encryption level or size.

19. The method of claim 18 wherein the distinct encrypted versions differ from each other by the manner that they were generated.
